I know the name of the site, but....My friend has a 2000 LS. The other day he took it to a shop to have a new flywheel and clutch put on. When they were done everything was fine and he drove straight home. The next morning when he started it up, it would idle normal and then the rpm's start to fluxuate(sp) between 800 and 1500. When he gives it gas nothing really happens and then the car dies. I don't see how this could have anything to do with the clutch/flywheel job, but does this sound familiar to anyone.
